trench effect

noun

The phenomenon of a fire rushing quickly up an inclined surface, due to a combination of the Coandă effect (which causes the fire to hug the inclined surface) and flashover (where the surface of a space near the fire — in this case the surface of the more elevated regions of the incline — is heated until it self-ignites).
